adapter into the hose coupling. Do NOT overtighten. Install the appropriate nozzle (fire, foam, or
slurry) on the extension pipe. Screw the ball valve into the small end of the adapter and draw it up tight.

During the cleaning process, you also should be inspecting the gun assembly.
In the inspection you should --
Inspect the threads for nicks, burrs, or other damage.
Inspect the ball valve body for cracks, pits, or other physical damage.
Inspect the gun handle for cracks, chips, twists, bends, or other damage that would interfere with
efficient operation.
Inspect the extension pipe and adapter for cracks, bends, holes, being out of round, or other damage
that would affect operation of the gun assembly.
Test the gun assembly by operating the pun handle.
Notify organizational maintenance personnel if the gun assembly must be repaired or replaced.
Nozzles
In servicing the nozzles, clean the fire hose water and foam nozzles and the slurry nozzle. Use soapy
water and a small brush. Inspect the nozzles. See that gaskets and washers are installed and are not
damaged. See that the threaded fittings are clean and undamaged. Test the slurry nozzle by rotating the
orifice-and-deflector assembly. Test the fire hose water nozzle by rotating the orifice-and-deflector
assembly. Test the fire hose water nozzle by rotating the sleeve. See
